LOCKING DEVICE Filed Dec. 25, 1950 Patented Sept. 20, 1932 UNITEDSTATES- PATENT OFFICE LOUIS D. SCHMIDT, OF POND DU LAC, WISCONSIN,ASSIGNOR T0 COMBINATION DOQR COMPANY, OF FOND DU LAC, WISCONSIN LOCKINGDEVICE Application filed December 23, 1930. Serial No. 504,333.

This invention relates to improvements in looking devices of thecharacter set forth 1n the United States Letters Patent #1,149 ,0 90,and has for the primary object, the provision of means for increasingthe pressure or holding power of the device when moved from an unlatchedposition to a latched pbsition for more efficiently locking the closureor the like to the frame thereof and thereby assuring a weather-proofconnection between said closure and frame and obviating any poss1-bility of rattles or unnecessary noises Another object of this inventionis the provision of an offset in the lever to provide a finger gripdisposed over the rim or attaching flange of the cup or casing that thedevice may be more easily actuated by the increased leverage providedthereby.

A further object of this invention is the provision of a locking deviceof the above stated character which will be simple, durable andefficient, and which may be manufactured and sold at a comparatively lowcost. 1

With these and other objects in view as will become more apparent as thedescription. proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts to be hereinaftermore fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe accompanying drawing and following description, in which Figure l isa fragmentary elevation illustrating a locking-device constructed inaccordance with my invention.

Figure 2 is a similar view showing the locking element inv lockedposition.

Figure 3 is a vertical transverse sectional view showing the device inan unlocked position.

Figure 4 is a similar view showing the de vice in locked position.

Figure 5 is a perspective view illustrating the locking element.

. Figure 6 is a perspective view illustrating the fastening element orscrew.

Referring in detail to the drawing, the numeral 1 indicates a closure orthe like associated with a frame 2 grooved or slotted to provide akeeper 3 in which the locking element 4 is moved to secure the closureagainst relative movement with respect to the frame 2. The closure 1 isprovided with a seat or positely disposed shoulders 14 are formed on theshank 12 and head. 13 and are received in a slot 15 of the latch element4.

The latch element 4 comprises an elongated head 16 having rounded orarcuate shaped ends 17 and substantially straight sides 18 that thelatch element may rotatefreely within the cup or casing 5 in eitherdirection. A handle 19 is formed on one of the straight sides 18 of thehead 16and is offset to extend outwardly of the cup or casing 5 over theflange 9 to permit a person to easily obtain a firm grip on the leverfor moving the head 16 into and out of engagement with the keeper andthe offset provides a very desirable leverage for facilitating theactuation of the device.

After the device has been applied to the closure 1 as shown in thedrawing, and with the fastener 11 threaded into the closure, themovement of the latching element 4 into a position for disposing aportion of the head 16 in the keeper 3,,the screw or fastener 11 will begiven a quarter of a turn and owing to its threaded action with theclosure 1 an increased binding action of the head 16 in the keeper 3will be provided, and more efiiciently lock the closure to its frame byurging the closure toward the frame and thereby establishing aweather-proof connection,

and also will obviate rattles or unnecessary noises by the binding ofthe closure to the frame. The movement of the lever 19 in a reversedirection disengages the head 16 from the keeper 3 and also provides aquarter of arr-.4 My

gaging the walls of the slot to rotate the fas-.

a turn to the fastener 11 in a reverse direction relieving the bindingaction.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in Y construction,combination and arrangement of parts may be made without departing fromthe spirit and scope as claimed.

Having thus described my invention, what I claim is:

A latching device comprising a substantially semicircular cup shapedplate secured to a movable member and having an opening, an elongatedhead located within the clip shaped plate and rotatable to disposed oneend thereof into and out of a keeper of a nonmovable member, said headhaving a slot intermediate the ends thereof, a headed screwthreadedfastener extending through the slot and opening and threaded to thenon-movable member, lugs on said fastener and entener by the rotation ofthe head and cause binding of the head against a wall of the keeper whensaid head 15 rotated in a direction for positioning a portion thereof inthe keeper, and a handle formed in one edge of the head and ofiset andextending outwardly of the cup shaped plate for permitting manualrotation of the head in either di-- rection.

In testimony whereof I afiix my signature.

LOUIS D. SCHMIDT.
